Warren Buffett's successor is making a decisive move with Berkshire Hathaway's (BRK.A.US, BRK.B.US) enormous cash pile. In the second quarter, the conglomerate significantly increased its stakes in both Delta Air Lines (DAL.US) and Alphabet (GOOGL.US), the parent company of Google. Greg Abel, who took over as CEO, is now starting to deploy the massive cash reserves more aggressively, ramping up stock purchases and acquisitions.

According to a regulatory filing released on Friday, during Abel's second full quarter at the helm, Berkshire added 17.5 million shares of Delta Air Lines. By the end of June, the value of Berkshire's stake in the airline had swelled to $5.37 billion. Simultaneously, the company made a massive bet on Alphabet, purchasing 48.1 million new shares in the second quarter. By mid-year, the value of its Alphabet holdings had reached $37.8 billion, making it Berkshire's third-largest stock holding.

When Berkshire reported its second-quarter earnings, it disclosed that net stock purchases for the quarter reached nearly $20 billion. The company also spent about $4.5 billion on share buybacks. This marks a clear shift in Berkshire's capital allocation strategy. As investments and buybacks have expanded, the company's cash reserves have started to decline. By the end of June, Berkshire held $365.5 billion in cash, down $31.5 billion from the record $397 billion it held at the end of March, though the overall cash level remains historically high.

Why the shift matters

In the final years of Buffett's leadership, large-scale investments and acquisitions were relatively cautious, as he frequently deemed the market to be overvalued. Since Abel took over, the company has pushed multiple multi-billion-dollar deals in the second quarter, demonstrating a more proactive approach to deploying the cash accumulated over many years. One notable move was the $6.8 billion acquisition of homebuilder Taylor Morrison Home, a deal completed last month that continues Berkshire's long-favored value investing style.

On the other hand, Berkshire invested $10 billion in Alphabet to support the tech giant's investments related to artificial intelligence. For a company with a traditionally conservative investment style, this represents a significant shift toward allocating more capital to emerging fields like AI.

Looking at the bigger picture

From the significant increases in positions in Alphabet and Delta Air Lines, to the nearly $20 billion in net stock purchases and $4.5 billion in stock buybacks, and the continuous push for large acquisitions and AI-related investments, Berkshire under Abel is gradually accelerating its capital deployment. While the company still sits on over $360 billion in cash, its investment strategy is now clearly more aggressive compared to the cautious stance of the previous few years.
